Silver jewelry maintenance methods: Today's silver jewelry rarely uses pure silver, generally using copper alloy plating silver. The hardness of the silver jewelry is improved to meet the needs of various colors, styles and inlaid jewels.

The silver cloth is generally made of high-quality pure cotton as a substrate, and is added with polishing powder and glazing and decontaminating materials. Some advanced silver cloths are also added to nano-abrasives and glazing materials, which are specially processed. Silver cloth is suitable for wiping platinum, gold, silver and electroplated jewellery and products with rust on the surface, making jewelry and utensils as bright as new. The silver cloth contains silver maintenance ingredients, which can't be washed. After washing, it becomes ordinary glasses cloth.
